Abstract

In one embodiment the present invention includes a computer-implemented method of self debugging a computer program operating in a distributed processing environment. The method includes detecting a fault in a plurality of processing devices and classifying the fault according to fault classifications. The fault classifications have corresponding responses. The method further includes executing one of the responses in accordance with the fault having been classified. The method further includes revising the computer program according to the response. This method may be embodied in a computer program or executed by a computer system. In this manner, the computer program performs self debugging.
